A target shell monitoring device 4 that monitors an attitude and a position of the target shell Tg1, a compression laser output device 5a that irradiates the target shell Tg1 with a compression laser light LS1, and a heating laser output device 6 that irradiates the target shell Tg1 with a heating laser light LS3 following the compression laser light LS1 are provided. The target shell Tg1 has a hollow spherical shell shape, includes an approximately spherical space Sp on an inner side thereof, includes at least one through hole H1 connecting an outer side thereof and the space Sp, and includes, on an outer surface Sf1 thereof, irradiation areas Ar1 and Ar2 to be irradiated with compression laser lights.

A compact, simpler, more economical ICF target chamber and reactor design that maintains a low internal pressure, sub-atmospheric, and very small neutron flux on any pressure bearing vessel or steam generating mechanism. The present invention reduces radiant target emission towards the nearest wall of the hohlraum wall and/or sleeve material so that the radiation from target burn exits the end of the hohlraum through a wall material sufficiently thick to contain the target drive radiation, but becomes transparent to the target emitted radiation. The compact converter contains the energy released by the ICF target and converts it into usable heat to create steam. It also converts the excess neutrons, from the ICF target, into tritium. This is then collected with the unburnt fuel tritium.

Methods, devices and system for asymmetric inertial confinement fusion are disclosed. One method includes a fixing in position a target capsule comprising an inertial confinement fusion fuel, where the target capsule is substantially spherical. The method further includes for applying an oscillatory compression to the target capsule. The oscillatory compression includes compression at a first time in a radial direction orthogonal to a diametric axis of the target capsule, and compression at a second time along the diametric axis to drive the target capsule into driven into an ovoid shape. The oval shaped target can implode upon being further driven at a third time.

A method of imploding an Inertial Confinement Fusion (ICF) target may include directing laser energy into a hohlraum, where a target is disposed within the hohlraum that includes an ablator layer, a shell disposed within the ablator layer, and a fuel region disposed within the shell. The method may also include ablating the ablator layer in response to the laser energy being directed into the hohlraum, and generating a single shockwave that is driven inward through the ablator layer. The method may further include impulsively accelerating the shell inward when hit by the single shockwave, and compressing the fuel region by the inward acceleration of the shell.

A nuclear fusion reactor includes a geodesic-shaped reaction chamber having at least j planar faces, where j equals 2, 6, 8, 12 or 20 and j conical plasma injectors (CPIs) for creating circular rings of neutral plasma. Each CPI includes a conical inner cathode electrode disposed coaxially within a hollow conical outer anode electrode, the space between the anode electrode and the cathode electrode forming a converging conical plasma channel for creating circular rings of neutral plasma, the converging conical plasma channel accelerating the plasma fuel into a converging plasma ring that comes to a focus at the center of the reaction chamber. The angle between axes of adjacent CPIs defines a CPI face angle, the angle defined by the converging conical plasma channel at its apex defining a CPI convergence angle, wherein the CPI convergence angle is approximately half the CPI face angle.
